Answer:
Explanation:
1. A measure of how quickly velocity is changing is the acceleration
Acceleration is the rate of change of velocity with time. The rate at which a body is changing its velocity is known as the acceleration.
It is measured in the unit m/s²
2. Speed in a given direction is the velocity
Velocity is a vector quantity which measures the magnitude of motion in a specific direction. It is simply speed in a given direction.
When we say a motorcycle travels at the rate of 5m/s due east, we are describing the velocity of such body.
3. Force that resists moving one object against another is the friction
Friction is a force that opposes motion. It prevents a body from moving.
4. Measure of the pull of gravity on an object Weight
Weight is a measure of the amount of gravitational force on a body. It is mathematically expressed as;
W = mg
W is the weight, m is the mass and g is the acceleration due to gravity
5 Tendency of an object to resist a change in motion is inertia
Inertia is the tendency of body to resist change in motion. It is the ability of a body to remain in a perpetual state of rest.
6 Size is the magnitude
Answer:
Molar volume of gases
One mole of any gas has a volume of 24 dm3 or 24,000 cm3 at rtp (room temperature and pressure). This volume is called the molar volume of a gas.
This equation shows how the volume of gas in dm3 at rtp is related to the number of moles:
volume of gas at rtp = number of moles × 24

Answer:
Carbon monoxide + hydrogen → methanol
Explanation:
The given options are:
Carbon monoxide + methanol → hydrogen
It is incorrect because this word equation state that carbon monoxide and methanol react to form hydrogen.
Methanol → Carbon monoxide + hydrogen
It is incorrect because this word equation state that methanol form Carbon monoxide and hydrogen.
Carbon monoxide + hydrogen → methanol
This is correct because this stated that carbon monoxide and hydrogen react to form methanol.
Methanol + hydrogen → carbon dioxide
This is incorrect because this word equation state that methanol and hydrogen form Carbon dioxide.
